Journalists routinely live-tweet high-profile criminal trials, a practice that raises questions about access to justice and the principle of open court. Does social media open up the justice system? There is a normative debate in the literature about the use of Twitter and social media in the courtroom. This paper takes on this debate by exploring the relationship between digital technologies and criminal justice. Through a systematic examination of journalists’ tweets during two key trials (Ghomeshi and Saretzky), we ask to what extent can the live-tweeting of court proceedings achieve greater access to justice in Canada? We argue that while the live-tweeting does provide more access to court, potentially furthering the principle of open court, the nature of this access provides little in the way of increased engagement with the public and its understanding of the legal system. This paper makes contributions to both the legal studies and digital politics literatures.
